Hi community. Your advice and perspective is greatly appreciated.
We are doing a site replatform and I fear that serious SEO fundamentals were overlooked and I am not getting straight answers to a simple question: How are we communicating to search engines the single URL we want indexed?
Backstory: Current site has major duplicate content issues. Rel-canonical is not used. There are currently 2 versions of every category and product detail page. Both are indexed in certain instances. A 60 page audit has recommends rel=canonical at least 10 times for the similar situations an ecommerce site has with dupe urls/content.
New site: We are rolling out 2 URLS AGAIN!!! URL A is an internal URL generated by the systerm. We have developed this fancy dynamic sitemap generator which looks/maps to URL A and creates a SEO optimized URL that I call URL B. URL B is then inserted into the site map and the sitemap is communicated externally to google. URL B does an internal 301 redirect back to URL A...so in an essence, the URL a customer sees is not the same as what we want google to see.
I still think there is potential for duplicate indexing. What do you think?
Is rel=canonical the answer?
In my research on this site, past projects and google I think the correct solution is this on each customer facing category and pdp:
The head section (With the optimized Meta Title and Meta Description) needs to have the rel-canonical pointing to URL B
example of the meta area of URL A:
What do you think? I am open to all ideas and I can provide more details if needed.
